The washing of denim garments is a special part. Therefore, the washing process of denim garments must be clear to the denim development enterprises. Generally speaking, there are mainly the following types:

1. GARMENT WASH

Ordinary washing is ordinary washing, but the washing that we are familiar with is changed to mechanized. Its water temperature is about 60°-90°C, plus a certain amount of detergent. After about 15 minutes of ordinary washing, the water is softened. It can make the fabric softer, more natural and cleaner visually. Usually according to the length of washing time and the amount of chemicals, general washing can be divided into light general washing, general washing, and heavy general washing. These three washing methods have no obvious boundaries.

2. Enzyme Wash

Enzyme is a kind of cellulase, which can degrade the fiber structure at a certain pH value and temperature, so that the fiber surface is lost, so that the surface smoothness and softness of the gai shan fabric can be faded more gently. Fading (produces a "peach skin" effect), and gets the softening effect of chi jiu. Stone can be used together or instead of stone. If it is used together with stone, it is usually called ENZYME STONE WASH.

3. STONE WASH

Stone washing is to add a certain size of pumice stone to the washing water to polish the pumice stone and the clothes. The water level in the sanding tank is performed at a low water level at which the clothes are completely immersed, so that the pumice stone can be in good contact with the clothes. It can be washed or rinsed before stone grinding, or rinsed after stone grinding. It can be washed with yellowstone, white stone, AAA stone, artificial stone, rubber ball, etc., to achieve different washing effects. After washing, the cloth surface will appear gray and old, and the clothes may be slightly to severely damaged.

4. BLEACH WASH

In order to make the clothes have a white or bright appearance and a soft feel, the clothes need to be rinsed, that is, after ordinary washing with clean water, they are heated to 60°C, and an appropriate amount of bleaching agent (bleaching agent) is added according to the depth of the bleaching color. , Make the color to the board consistent within 7-10 minutes. After the clothes are bleached, the residual bleach in the water is neutralized with large (small) soda (Na2CO3, NaHCO3) to completely stop the bleaching. After clean water, add detergent, fluorescent whitening agent, hydrogen peroxide, etc. in water temperature of 50°C for washing, neutralizing the PH value, fluorescent whitening, etc., and then performing softening treatment.
Rinsing can be divided into oxygen bleaching and chlorine bleaching. Oxygen bleaching uses the oxidation of hydrogen peroxide at a certain pH and temperature to destroy the dye structure, so as to achieve the purpose of fading and whitening. Generally, the surface of the bleached cloth will be slightly red. Chlorine bleaching uses the oxidation effect of sodium hypochlorite to destroy the dye structure, thereby achieving the purpose of fading. Chlorine bleaching has a rough fading effect and is mostly used for rinsing indigo denim. After bleaching the board, the residual chlorine in the water and clothes should be neutralized with high waves to stop the bleaching, and then stone grinding after bleaching is called BLEACH STONE WASH.

5. Fried snowflakes (pickling)

Fried snowflakes are dry fried without adding water. The dried pumice is soaked with potassium permanganate solution, and then it is directly polished with the clothes in a special rotating cylinder. The pumice is polished on the clothes, so that the potassium permanganate will oxidize the friction points. Fade the cloth surface irregularly, forming white spots resembling snowflakes.
The general process of snowflake washing is as follows:
Potassium permanganate soaked in pumice stone---pumice stone and clothes dry grinding---snow effect on the board---take out the clothes and wash the stone dust on the clothes with clean water in the washing tank---oxalic acid neutralization (dechlorination)---washing- – Upper softener – – Centrifugal dehydration machine dehydration – – Rotary cage dryer drying.

6. Hand brush

Arrange from weak to strong effect: hand rub <sanding <spray monkey. Sometimes it can be combined with hand rubbing + spraying monkeys, sanding + monkey spraying, but be careful not to use hand rubbing and sanding together, because sanding will completely cover the effect of hand rubbing. Spraying monkeys is more rigid, and is often combined with hand rubs to achieve a natural excess effect.

7. SAND WASH

For sand washing, some alkaline and oxidizing additives are used to make the clothes have a certain fading effect and old feeling after washing. If it is matched with stone grinding, a layer of soft frosty white fluff will be formed on the surface of the cloth after washing, and some softeners are added. It can make the fabric soft and soft after washing, thereby improving the wearability.
Sand washing agents generally require bulking agents, sand lotions, and softeners. According to fiber type, fabric structure and tightness, select the puffing agent and concentration, temperature, time and other puffing conditions. When pure cotton clothes are sand washed, alkaline puffing agents such as soda ash can be used for puffing treatment; after the clothes are puffed, the fiber Loose, and then rub with the help of special sand washing, so that the loose surface fibers will produce feng man soft hair; the softener used for sand washing is required to be soft and waxy, so that the fabric can increase weight, and the drape must be obvious gai shan . Therefore, this kind of softener should have a long carbon chain and cationic properties, which can be adsorbed on the fabric to achieve the purpose of weight gain.

8. Sandblasting (SPRAY STONE WASH/ SAND BLAST)

Sandblasting is also called playing sand. Use special equipment (it is a kind of large electric toothbrush, which is only a roller type) to polish on the cloth, usually with an inflatable model. (The denim sandblasting machine for apparel fabrics uses compressed air to feed brown corundum sand from the sand storage tank into the sandblasting nozzle, and blast the surface of various denim garments. It can spray a variety of whitening effect patterns.)
The goal is to obtain a local wear effect. Usually before the denim clothing is washed normally, the strong air pressure generated by the air compressor and the sand blasting device ejects alumina particles to complete the sand blasting process. Under the action of strong airflow, alumina particles are sprayed on the surface of the garment at a very fast speed. Abraded locally, the fibers of indigo dye peel off the surface of the fabric under the action of friction.

9. Monkey wash

Usually after the denim clothing is washed normally, the potassium permanganate solution is sprayed on the clothes with a spray gun according to the design requirements, and a chemical reaction occurs to fade the fabric. The concentration and spray volume are used to control the degree of fading. After spraying the monkey water, rinse it with water. Spraying monkeys can form a variety of shapes, such as cat whiskers, white strips and so on. (The whiskers can also be wiped by hand).
The essential difference between sandblasting and sandblasting is that the former is a chemical action, and the latter is a physical action. From the effect point of view, the former fades uniformly, the surface layer and the inner layer are faded, and a strong fade effect can be achieved. In the latter, only the surface layer has faded, and the physical damage of the fiber can be seen.

10. MOUSTACHE EFFECT

Cat's whiskers can also be WHISKER in English, but WHISKER's statement. Cat whiskers are a kind of handbrake (hand brush, HAND BRUSH), it is just ground into the shape of cat whiskers. It can also be achieved by spraying monkeys and using a cat's whisker mold. There are three types of whiskers that are currently popular:
1. It is an ordinary cat's whiskers, that is, as mentioned above;
2. It is a three-dimensional cat whisker (the cost is more expensive). The difference between it and the ordinary cat whisker is that it has layers, usually two layers of light and dark, and one light and one dark make it three-dimensional;
3. Hand fold cat's whiskers, the hand fold here can be hot pressing or seam. Hot pressing is formed by applying syrup after hot pressing, and it is formed after washing. It is characterized by creases. If it is subjected to high temperature setting, the three-dimensional effect will be maintained for a long time. The effect can be achieved by washing with water. The high point of the seam is washed white, and the low point of the seam is the original color of denim, and the shape is irregular, special and strong.

11. CHEMICAL WASH

Chemical washing mainly uses strong alkali additives (NaOH, NaSiO3, etc.) to achieve the purpose of fading. After washing, the clothes will have a more obvious sense of oldness. Add softeners to make the clothes soft and feng man.
If stone is added to the chemical washing, it is called CHEMICAL STONE WASH, which can enhance the fading and abrasion effect, so that the clothes have a strong sense of worn-out. The fossil washing combines the chemical washing and stone washing effects. After washing, it can achieve a kind of distress and fluffing effect.

12. PIGMENT DYEING

At present, this washing and dyeing method is popular in many European countries. Pigment wash / pigment dyed wash, also called "single-side coating / paint dyeing", means that this washing method is specially designed for clothing dyed with paint, and its function is to consolidate the original Brilliant color and increase the softness of the hand feeling. At present, this washing and dyeing method is popular in many European countries.
Denim clothing has taken root on the land of China. It has been half a century. The MinZu brand, which has been deeply cultivated for 23 years like Jaeger Jeans, has been born. Artisan Fashion Design Institute uses ZhongGuo elements and combines Korean fashion trends to bring cool, high-grade, DuLi independent product series to young people nowadays, and select materials, styles, tailoring, sewing, outsourcing, and buttons. In every aspect, Zhenzheng has achieved the fine craftsmanship that surpasses the world's major brands.

13. Destroy wash (DESTROY WASH)

After the garment is polished with pumice stone and treated with additives, some parts (bone position, collar angle, etc.) will be damaged to a certain extent, and the clothes will have a more obvious worn-out effect after washing. You can also cut the cloth surface at the designated position first, and then wash it with water to achieve the effect of abrasion.
